Wehrli Custom Fabrication -10AN Extended Turbo Oil Drain Fitting Kit (Black Anodized) T3/T4/T6 Midframe Turbos
The Wehrli Custom Fabrication -10AN Extended Turbo Oil Drain Fitting Kit is a precision-machined solution designed to simplify turbo oil drain line installation and maintenance. This billet aluminum adapter flange features a 4-inch extended -10AN male fitting that lowers the threaded connection point away from the tight confines of the turbo center section, making it much easier to reach with a wrench. The kit includes a reusable O-ring seal that eliminates the common issues of leaking or torn paper gaskets at the turbo drain port. It is compatible with T3, T4, and T6 midframe turbochargers that use standard 2-inch on-center bolt spacing. CNC-machined from billet aluminum and finished in durable black anodizing, this fitting kit provides a clean, professional installation while improving serviceability and reliability in high-performance turbo setups.
